All while offering an impressive amount of interior living space. Not to mention getting a wet bath integrated into the driver’s side, which your family is sure to appreciate if you like to camp away from RV parks and campground facilities.
Do Diesel Engines Get Better MPG?
Diesel engines tend to be larger and more fuel-efficient than the same-size gasoline engines.
They also tend to produce more torque, which makes them a preferred option for families who like to tow a car, SUV, or boat behind them.
Though some of the fuel efficiency of a diesel engine is offset by the fact that diesel fuel tends to cost a little more than gasoline.
Which Is Easier To Drive – Class A Motorhome or Class B?
Class B motorhomes tend to use tighter, slightly smaller chassis like the Mercedes-Benz Sprinter 2500.
This means they handle like the full-size cargo van that they draw their floor pan and frame from.
Most people will tell you that this makes them easier to drive than typically larger Class C motorhomes.
Which Is the Better Type of Motorhome for a Family?
The vast majority of Class B motorhomes will only sleep 2 or perhaps 3 people. Whereas you can find Class C motorhomes that can sleep 4 to 6 or possibly 8.
You need to take this into account when shopping for the best diesel RV under 30 feet.
If it’s just you and a significant other, with perhaps one child, you might be able to get by with a Class B motorhome.
If you have more than two children, then you will likely need to restrict your research to Class C diesel RVs.
Conclusion
There are a lot of great Diesel RVs under 30 feet to choose from in the Class B and Class C motorhomes.
The one that’s best for you, will depend on the number of people you need to travel with, as well as the kind of power and interior room you prioritize.
